"For some time she was content with threats, and this threat of a punishment that was quite new to me appeared very terrible; but, after it had been carried out, I found the reality less terrible than the expectation; and, what was still more strange, this chastisement made me still more devoted to her who had inflicted it. It needed all the strength of this devotion and all my natural docility to keep myself from doing something which would have deservedly brought upon me a repetition of it; for I had found in the pain, even in the disgrace, a mixture of sensuality which had left me less afraid than desirous of experiencing it again from the same hand. No doubt some precocious sexual instinct was mingled with this feeling."
